Emerson MICRO MOTION F-SERIES SENSOR - Manual (Page 14)

12 Sensor Installation: F-Series
Orienting the Sensor
Step 2 Orienting the Sensor
The sensor will function properly in any orientation if the sensor tubes remain filled with process fluid.
Micro Motion recommends orienting F-Series sensors as shown in Figure 8.
Figure 8 Recommended sensor orientations
Self-draining applications
The F-Series sensor is self-draining when it is installed in a vertical pipeline (see Figure 8). For CIP
applications it is recommended to use the generally accepted flow velocity of at least 1.5 m/sec for cleaning
the sensor.
Flow direction arrow
The sensor has a flow direction arrow (see Figures 1–5) to help you configure the transmitter for flow
direction. If possible, install the sensor so that the flow direction arrow matches actual process flow.
Vertical pipeline
If the sensor is installed in a vertical pipeline, liquids and slurries should flow upward through the sensor.
Gases may flow upward or downward.
